Apnlieetion led February 5. SM. Serial No. 618,813'.

ToaZZ io/inni it ma@ concern citizen of the United States, residing at Worcester, in the county oi"- l'lvoreeeter and f Be it known that l, HORACE ilarnn, a

State of Massachusetts, have invented a new and' useful Vleft'- Replenishing Loom, of which the following is a specification..

Thisinvention relates to a weft replenish ing loom of the type in which a magazine mounted on. a fixed part of the loom supports a plurality' of illed weft carriers or bobbinsin position to be automatically transferred to the shuttle-tof replace a ,cornpletely er substantially exhausted weft carrier, the operation of the transferring mechanism being controlled by a :suitable weftY detecting device.

More speciieally, my invention in its principal. features relates te. that class of weft replenishing: looinsin which the magazine contains two or more compartments having weft carriers with weft of di erent .characteristics therein and also having a drop box or shuttle shifting mechanism for periodically changing the active shuttle.

Drop hoi: or multi-color looms have lleretoiore been provided With magazines and With transferring mechanism but the transfer has commonly taken place at the extreme forward point of the movementvof the lay during the momentarydwell of the shuttle at the forward dead center. ln high lspeed looms, this dwell is extremely brief and the necessary speed of operation Aof the 'transferring mechanism frequently results Ain breakage of parts and damagel to the weft carriers. e A

A transferring device is shon'nin United States Letters-Patent to `J`liillou, No. 1,082,390, granted December :23, 1913, in which the transferring mechanism is mounted upon the la)7 and moves therewith, being so arranged and operated that a large detector and the box shifting mechanism to portion of the revolution of the crank shaft.

which the advantages of the prolonged transfer period are realized, while at the same time the device is rendered applicable to nnilti-color operation. Accordingly, havecomoined a transiter. mechanism mounted to more with the lay with selective and controlling devices by which the transfer atented June Sy;

mechaeiisrn is caused to select a bobbin or ,weft carrier corresponding in type to the active shuttle and to thereafter transfer the selected hoh'oin to the shuttle.

in accordance with the objects thus `outlined, the present invention inthe preferred form shown in the drawings contemplates the provision, in a' weft replenishing loom, of select-ive and controlling" de iees coniprising a weft detector mounted on the trame of the loom, a gripping deviceor transferrer 'mounted to move with the lay, an indicator Jointly controlled bythe weft indicate the complete or substantial exhaustion ot nlhng in a particular shuttle, and

operative connections by which the grippinfr v device or transferrer is thereafter act'uate to select a hohhin corresponding in typev toA the active shuttle and to insert 4it in said shuttle. As the active shuttle may oe changed between the indication of the weftexliaizstion and the actual transfer of the 'oohhin or Weit carrier,` I also provide for ihesuspension of the transfer in such an event until the indicated shuttle againrbecomes the active shuttle. At the same time the' detectingr and transferring mechanism .isfiully available for use in the event of the exhaustion of the weft in any other active shuttle.

For the accomplishment 'of the ohjectsv above referred to, the invention comprises the several features and combinations of parts which will be hereinafter described and more particular-l5Y pointed out in the appended claims. i

A preferredl form of the invention is shown in the drawings 1n Which- Figure l is a side elevation oi a portion ot' a loom einliodying my invention, the A parts beingv shown in the position which they occupy during the normal operation of the loom. Fig. 2 is a partial front cle 'ation of alooinshowing the parts in the same position as in Fig. l; Fig'. 3 is a side elevation similar to Fig. l but showing the parte after f side elevation similar to Fig. '1, showing the u as parts in position to insert a fresh bobbin in the shuttle; Fig. 5 is a front elevation showing certain of the parts in a position corresponding to Fig. 3; Fig. 6 is a, detail view showingthe provision for resetting vthe indicator; Fig. 7 is a detail view of the gripping device or transferrer in the act of inserting a bobbin in the shuttle; Fig. 8 is a 'plan view of the gripping device in, position to seize a bobbin in the magazine; Fig. 9

.is a. detail view of the mechanism for shifting the eccentric supporting the cam which ,l

actuates the gripping device; Fig. 10 is a" devices in'normal position; Figs. 11 and12 4 show the delivery positions of the cradle operating devices for the lower and'upper compartments respectively, and Fig. 18 is a partial detail view of the magazine.

- l have shown the invention herein asembodied in a drop box or multi-color loom of ordinary typefhaving av magazine with a` plurality of compartments for weft carriers or bobbins of different characteristics at one 4side of the loom, and shifting shuttle -bo`x mechanism at the other side, the magazine being mounted at the rear of the lay vand a weft detector being provided upon the magenzine end of the loom.

The usual loom frame is indicated at 10 (Fig. 1) on which is mounted a magazine 11.

The lay is indicated at 12 supported upon the usual sword 13 and operated by crank arms 14 from a crank shaft 15.

The magazine 11 is of special -form and comprises a pair of end frames 16 and 17 (Fig. 2) maintained in spaced relation by.I connecting rods 18. Each of the end frames is provided with a pair of parallel substantially-vertical recesses 19 (Fig. l) which at their lower 'ends merge into substantially concentric forwardly-opening curved discharge portions 19a. T he'recesses in the end frame 16 are adapted to receive the butts ofl the weft carriers while`the recesses inthe.' end frame 17 are similarly adapted to receive theJips thereof.

Between the recesses or guiding portions 19 and 19a in the frame 17, a slot 20 (Fig. 13) is provided in the frame 17, the slot being parallel to the vertical portions 19 'of the recesses and concentric with the lower curved portions 19a. The ends ofthe weft threads are brought out from the weft carriers in the :magazine through the Slot 20 and are secured on a support 21 (Fig. 2) which is substantially over the cnter of movement of the lay. With this construction the weft threads are held under subst-.1ntially uniform tension as they advance through the curved portions of the magazine to the position from whichl they are trans-gy ferred to the shuttle and are subjected to nog unusual strain during the transfer.

A rocking gate or cradle 22 is pivotallyv mounted near the lower end of each com-V partment and is shown in its normal position bobbins within the compartment.

16 and 17. At one end of the cradle a stud 23 (Figs. 10 to 12) extends through the frame 16 and is provided upon the outer side 1 thereof with a segment pinion 24. The pinions 24 are in mesh with segment gears 25 i '.1 v* so which aref each provided withv operating arms or extensions 26.l A spring 27 nor- I lmally separates the gears 25 and maintains .Y detail view showing the cradle operatlng 'the cradles in the position shown in Fig. 1.

When the transfer of a bobbin is about to take place an operating device, to be hereinafter described, is brought into operative relation with one or the other of the arms y 26, turning the same-to move Athe cradle as Aindicated in the uppercompartment of Fig. I* i y Reference to this figure will show that the cradle in this position releases the lowermost bobbin while at 'the Sametime itprevents th escape ofthe next higher bobbin.rv

Furthermore, the cradle acts to rigidly7 sup; port the released bobbin against the thrust of the bobbin gripping or transferring mechanism.

A weft"z detector of one of the usual forms` y is essential forfthe o eration of my devicey and I have herein indicated at 28 (Fig. 1) a feeler of the type fully described in Let-Ir ters-Patent No. 972,722 issued to E. H. Ryon,

October 111910." This type of feeler is designed to operate `upon the substantial exhaustion of the weft upon the bo bin, causunderstood, however, that the utility of my invention is not dependent upon the use of any particular type of weft detector and'lv understanding of the present invention, itk

is suflicient vto state that under normal conj (litions the rod` 29 moves idly but that, as' soon nas the feeler indicates the substantial exhaustion of the weft in the shuttle, they i' rod 29 becomes operative upon the rod 34' (Fig. 2) and forces the same downward into` the position shown in Fig. 5. For a full de` auf.

1o`5` ing the insertion of a fresh bob in before 1f the weft is entirely run oil". It should be 10" that many of its advantages may be secured 1n connection with aweft fork or similar de-l i f the rod 34 swings the upwardly projecting portion 35a of the lever 35 to the left as`- viewed in Figs. 2 and 5.

.Referring new to the indicating mechanism `which enables the feeler to indicate the exhaustion of illing in a particular shuttle,

an indicating arm 38 (Figs. l and 2) is mountedupon a stud 39. secured to the loom side and is connected to swing transversely in front of the arm 35a of the lever 35. The arm 38 has mounted therein a plurality of indicating 'pins 40 (Figs. 5 and 6), each of which is adapted to be yieldingly retained in either one of two longitudinal positions by a spring pressed plunger 41. When the lever 35 is swung to the position shown in Fig. 5 by the depression of the rod 34 it operates to force one or the other of the pins 40 into the position shown in Fig. 5 in which the pin projects on the left hand side of the arm 38.

The upper end of the arm 38 is connected through a link 4l to a bell crank 42 mounted upon a bracket 43 secured to the loom side and in turn connected by a link 44 to any convenient part of the shuttle box operating mechanism at the opposite side of the loom so that it may receive a longitudinal motion dependent upon the indications of the`pattern surface or the movement of the shuttle boxes. rhrough these connections the arm 38 is moved to the right or the left as viewed in Fig. l in accordance with the raising or lowering of the drop shuttle boxes at the 0p posite end of the loom. This movement of the arm 3S brings one of the pins 40 in line with the lei er .The displacement ot-a pin 4() to the left lo* the lever 35 initiates a series of operations which result in the removal of a fresh bobbin from, the magazine and the placing of the sa mein -the active shuttle. The mechanism through Whichthese .results are obtained comprises in general a transterrer or gripping device mounted upon the lay, a

cam also mounted upon the lay tor operating the gripping device, and connections whereby the actuation of the cam is controlled Y through the indication of a pin 40.

The gripping dov-ice or transferrer 1s niountedupon a curved bracket 45 (Figi lf) secured to a casting 45a fastened to the back oi the lay on the magazine end of the loom. The gripping device comprises a rigid tramo 4T (Figs. 7 and 3) nivotally mounted upon a shaft 48 secured in the bracket 45, said frame (Figs. 7 and 8) is pivoted to the traine 47 has depending therefrom at one end a pair of spring fingers 54 which are adapted to grasp the butt of a bobbin When in their normal position shown vin Fig. l. The lever 5'3 is yieldingly held in this position by a VPlo spring 53a and may-be moved upward relatively to the frame 47 by contact with a projection 46a upon the back binder 46 as shown in Fig. 7 to release the butt of a bobbin grasped thereby. )Vlien the gripping de vicey is turned to the position shown in Fig. 3 to seize a freshbobbin in the magazine, the lever 53 comes in line with a rigid arm 55 secured upon the shaft 48 which prevents movement of the lever53- relative to the trame 47, and enables the spring fingers 54 to be force over the butt of a. bobbin.

The normalposition of the gripping device is that shown in Fig. l and suitable operating devices are necessarily provided for moving the"gripping device to the position shown in Fig. 3. These devices include a vertically movable rod 56 (Fig. l) vWhich is connected at its lower end to an arm 57 pivoted on a bracket 58 secured to the lay Ysword 13. "The arm 57 has mounted there on a roll 59 which coperates with a cam 60, the operation of which will be hereinafter described. At 'the upper end, the rod V56 is! screwed into a slotted arm 6l and is firmly held in place by a check nut 62. An arm 64 Figsql and 8) is secured to or formed integral with the rigid tra-me member 47 and has projecting laterally therefrom a stud 65.

This stud extends into .the slot 66 in the arm 61 and forms a sliding connection between the rod 5G and the gripping device.

It will be obvious that upward movement of the rod 5G Will turn the gripping device upon the shaft 4S and that the extent of angular movement ot the gripping device Will depend upon the vertical movement of the rod 56. By varying the limits of this vertical movement the gripping device may be swung into a position to seizea bobbin in either the upper or the lower magazine compartment. I

The devicesfor selectively' controlling and noel-ating thecam (i0 will now be described. The cam is mounted tor partial rotation upon nn'cccentric bushing (37 (Figs. l and D) "which is secured to a shaft G3 pivotallv mounted in bearings upon the lay sword 13 and which extends across the loom. At its opposite end, the shaft 68 is provided with a pinion G9 (Fig. 9) meshing. with a vertif vcally movable rack 70.- This raclgmay be operated in any convenient manner from the drop shuttle mechanism and :is herein shown as supported upon a stud 71 mounted in a bracket 72 secured to the box lifting rod 7 3. lVith these connections it will appear that vertical movement of the drop boxes will result in partial rotation of the shaft 68 and theeccentric 67, the rotation of the eccentric raising or lowering the effective center of rotation of the cam 60. Secured to orintegral with the. cam is an operating disk 74 (Figs. 1-3 and4) having a hook-shaped projection 75 formed thereon. An arm 76 is pivotally supported on a stud 77 secured to the loom side and has mounted thereon a roll 78. Under normal operating conditions the arm 7 6 4is supported in raised positionJby a latch 79 also mounted upon the stud 77. The hub of the latch has a notch in the end which coperates with a projection on the end of a collar 79a fixed to the stud 77, (Fig. 2) thus.

limiting the movement of the latch 79 and the arm 76. The lower end of the latch 79 normally contacts with the sideof an 11pwardly projecting arm 8O forming one part of a bell crank 81 pivotally mounted upon the'loomside at 82. Under certain conditions, which will he hereinafterdescribed, the armis movedto the left as seen in Fig. 5, thereby releasing the latch 79 and allowing the arm 76 to descend bringing the roll 78 in the path of the operating disk 74:. As the lay moves back, the disk and the cam 60 secured thereto vare then moved from the position shown in Fig. l tothat'shown in Fig. 3. This movement of the cam forces the lever 57 into -the'position' shown in Fig. 3, which in turn moves the rod 56 'vertically to swing the gripping device upon its sup'- porting member. l

llVhen the eccentric 67 is in the position shown in Figs. 1 and 3,'the-movement of the rod 56 will carrythe gripping device to its extreme upper position, in which it coperates with the upperV compartment of the magazine. Shouldthe drop boxes beshited the eccentric 67 will be turned to a posiy tion diametrically opposite to lthe position shown in Figs. l and and the gripping device will then coperate with the Ylower compartment. of the magazine.' Aisprilng 83 secured to the lay is flexibly connected with the cam 60 and acts to return the cam together with the operating parts and the gripping device to the position shown in.

' Fig. l when the cam is released from the arm- 76. The exact positioning of the gripping device is accomplished by thecoperation of the lligs 45 and 47a. A cam roll 84 is mounted dpon a collar 84 on the rod 56.

When the rod is raised to turn the gripping,

device to operative position, the roll 8412.

contacts with one or the other of the armsfY 26 (Figs. 10 to 12) to move one of the seg-.rig

ment gears 25 to rotate. the corresponding? the roll 84 operating the upper cradle. The

upward limit of the vertical n iovementv of therod 56 as determined by the positionof the' eccentric 67 will selectively control the,l the lower cradle" operation of the upper or by the roll 84. The following selective and controlling devices are provided which govern the movement of the bell crank 81 and the rew lease of the latch 79: The upwardly pro-l jecting arm 80 of thebell crank 81 has a.-

lug 85 upon its -r'ear side and a vertically lmovable' cam plate 86 (Fig: 6) pivotally.

mounted upon the vertically movable rod 29 (previously described)v is constantly reciproc-ated adjacent to .said lug. Upon its right side (as viewed in Fig. 6) the plate 86 is provided with a plurality of cam projections, the. plate being normally moveditol ward vertical position by a weak spring 87. and beingheld' Jfrom movement beyond ver.v

ticalposition.toward the right by a lng86j which projects Jfrom the side of the platet and contacts with the rod 29. The canal plate 86 remains' inoperative until one of:

the indicating pins AlO-is moved by the vice previously described 4to the position shown in Fig. 5, this movement of the pin being controlled by the weftv detector. The arm 38 is so positioned that the pin 40- cor; responding to the active shuttle is always in line with 4he cam plate 86. Upon the next upward movement of the rod 29' the cam ico projections upon the plate 86 will contact with the pin 4:0 and the cam Will be swung to the left as shown in Fig. 5. By this .movement the cam plate is forced again'st Ythe lng- 85 thus swinging the arm 80 to the left and releasing the latch 79. The release shuttle has been returned to the drop box side of the loom and it'may frequently lhappen that a drop box mechanism will operate 'of the latch takes place after the exhausted to change the active shuttle before the .eXf hausted shuttle is returned to the magazine end of the loom. ln' this event the connec;..l l 'tions previonslv described between the drop box mechanism and the indicating arm 38 act` to suspend the release of the latch and i the transfer of the bobbin, as follows: The y parts are so timedthat the drop box'mechanism will operatebefore the rod 29 is given its upward movement. In case the boxes are changed. the arm 38 will be moved to a different position thus bringing the indicated pin l0 out of line with the cam plate 86.

The cam plate will then continue inopera-v isc essere@ tiveiintil the exhausted shuttle again betlieoi'her pin 40 may be indicated and the proper bobhin selected, and trgnsferred regai-(liess of'the previous indication.

'mutable lmechanism is necessarily provided through which the actual transfer of the iiesli liolilnn to the shuttle may be pei'- orined. The shuttle box upon the magazine end of the looiii, indicated diagrainmatically at 5S. is mounted for vertical movement upon rods 519 which are vertically adjustable in ii casting Sil secured to a vertically movable lifter rod (Fig. A depending' aini Ell (Figs. :2 and is pivotally mounted at 9) upon a co..ar secured to the rod @il and has near its lower end a pro jecting lug .(23. .-lsecoiid collar 9i is mounted to slide freely upon the rod 90 and is connected by a link to a lever, 96 which is periodicallyr operated by a. ca in 97 (Fig. l).

The collar 9i has-a rib 98 projecting troni its front side. which rilo is provided vfitli a notch 99 iiiwii'ited, at tiiiil to receive the lug lli-l. The @pending ariii Ul has formed therein a cani slot and a leverllll pivotally iiiouiitd upon the lool/ii side carries at oiic cnil a long stud 102 which extends into the slot 1GO in all positions of Ythe lay. The lever lill is iioiiiially maintained iii the position shown in Fig. 2 by a spring 103 secured to the looiii side.

ver 10i and at its upper end is connected to the hell crank Si. -`When the bell crank and lever are in their normal positions, the stud 102 is near the iipner end oi" the slot itil) and maintains the depending arm ill in such aposition that the lug 93 is clear et the notch 99. Viiiler these condi-tions the vestical reeiprocation ,of the collar 9i is inefective to produce movement ofthe lifter rod 90. lfhcii. however. the bell crank 8l. is moved hv thecaiii plate SG to initiate the transfer o'l' a =fresh liol'ibin, the lever lOlY is simultaneously moved to the position shown in Fig. 5, permitting the lug 93 to enter the notch thereby connecting the rod 90 with the sliding-collar Gn its next vertical movement, the collar 94' will move the rodi 90 iipiviii'd,'theieb v lifting the shuttleboii: 88 to the position shown in Figs, causing thefiesh bobbin to be inserted inthe shuttie. As the shuttle box rises, an upwardly projectingr linger 46 (F ig. 7) mounted on the baci?. box plate i6 raises the lever andk the spring fingers 54 relative tol the rigid frame l?. thus releasingthe bobbin from theingers 134. |The empty bobbin is forced downward through the bottoni of the shuttle, as shown in Fig. 'i'. andan opening is link lOl is ad. Agustalily secured at its loivei' end to the leprovided in the bottoni of the shuttle boi: 8S to permit the empty bohbin to pass therethrough.

An arm (Figs. il. and 3) is rigidly secured to one of the rods 8) and, when moved upwardly with the shuttle box, it contacts with the latch 79. retin-nin the 4latch and the arm 7G to their normal raised position. lVhile held in this position the bellcrank 8.1 is moved to the right by the spring lUS so' that the upwardly. projecting arin 8O again becomes operative to maintain the latch 79 in the position shown in Fig. l. The resetting of the indicating pin 40, after it has performed its function by causing the release of the latch 79, is accomplished by an additional cam projection 86b (Fig. 6) upon the right side of the cam plate 86. As the plate continues its upward movement after releasing the latch 79, this lower projection contacts with the 'pin Ll0 and forces it back toiiori'nal position against the yielding resistance of the plunger fil. The iesistaiiceyot the plunger is sufficient to move the cani plate to the left to the position shown in Fig. 5, thus releasing vthe latch 79 as the plate rises but further movement to .the lei't is prevented by the'opposed lugs which support the spring S7.

.iltliough the operation of the different elements ot' my invention has been described in detail. Va brief statement of the general operation of the device :is a Whole may be found desirable. liVith the parts in noi-inni position, partial or complete exhaustion of vtilling in the active shuttle will be eective through the feeler mechanism to cause downward movement of the rodel, siving ing the upwardly projecting portion 35E of the lever to the left and forcing one of the indicating pins i() into operative position. This occurs upontlie extreme forward increment the lay'ivitli the shuttle in the magazine end of the loom. rihe shuttle is then thrown to the drop box side ot' the loom and the cani plate 8G begins to rise. it there has been no change iii the act-ive shuttle, the indicated pin l0 forces the cam plate to the lett, carrying with it the arm 8G and releasing the latch 79. '76 vvith its roll '78 is thus loivered into the path of the hook-shaped projection 75 upon the disk 7l. rfhis takes place during the forward movement of the lay While the shuttle is still at the drop box end of the loom. As the lay again moves back, the cani roll 78 turns the cam 74 upon its eccen tric hearing, raising the lever 57 and the rod 5G, and turning the gripping device into in operative position opposite one or the.

meanwhile supporting the bobbin against the rearward thrust of the gripping device. While the `bobbin is being seized bylthe gripping device, the shuttle is again thrown to the magazine end of the loom. Duringvthe ensuing reciprocation of the lay and before -it again returns 4to rearmost position, the shuttle box 88 is raised and the fresh bobbin is inserted in the shuttle. Asthe latch 79 and the indicated pin 40 have been reset as previously described, all of the parts are again in normal positionand the loom continues its operation in theusual manner. The suspension of the transfer, in the event of a change. in the active shuttle be'- tiveen the indication and the actual transfer, hasbeen fully described. p

Where the Word bobbin occurs in this description or in the claims it is to be understood broadly as covering any of the ordi-A nary types of wett carrier and Where refer-' ence is made to the exhaustion of the weft,i

the reference includes bot-h the partial eX- haustion determined by a detector of the feeler type and the complete exhaustion f indicated by the ordinary weft fork, unless otherwise defined. Y l
